The size-Ramsey numberof a graphis defined as the smallest integermso that there exists a graphGwithmedges such that every 2–coloring of the edges ofGcontains a monochromatic copy of. Answering a question of Beck, Rödl and Szemerédi showed that for everythere exists a graphonnvertices each of degree at most three, with size-Ramsey number at leastfor a universal constant. In this note we show that a modification of Rödl and Szemerédi’s construction leads to a bound.
